Reshared post from +Platinum Apps
Vita for Facebook v3.5 has just been released and is available now on Google Play and Amazon Appstore (and maybe sometime in the next couple of weeks on Samsung Apps, given their painful approval process) so get it while it's hot.
Faster launching, loading & displaying posts.
Improved (and faster) login process.
Fixed issue with notifications screen not displaying properly in landscape orientation (tablet version).
Update to resolve July Facebook API changes.
Lots of other bug fixes & tweaks throughout the app.
